    almost identical to my 85 spec japanese market GB500.

    i'm in melbourne , Australia - bought it in the UK when i lived there in approx 2003 and imported it to Australia as a personal import in 2006.

    the Uk road salt wasnt kind the the orig honda exhausst - so put an aftermarket stainless steel one off an XBR in the UK - but it looked crap.

    finally finished up with a 'jack batson' one from the USA when back in australia

    I have an oil tank question-Is there some form of non-return valve that stops all the oil in the tank from ending up in the sump?-I ask this as a mate has fitted a larger oil tank to his GB that has a 650 Dominator motor fitted-Would this not overfill the sump?

    There's a check valve in the pump to keep the tank from draining down , but with age they start to leak down. It doesn't hurt anything. On older bikes it's best to check the oil immediately after shutdown or while running , to avoid a low reading when it's actually full.

    Review of Oxford heated grips

    I had been using electric glove liners in winter but got tired of plugging and unplugging every time I got on or off the bike, plus I found the wiring running through my jacket to be a hassle. So I decided to try the Oxford heated grips and thought I'd share my impressions. In short, I love them! They are very well made and the controller is very compact and user friendly. Plus the company has a great reputation for customer service. If one grip or any other part gets damaged it can be purchased individually. I was worried that the top sides of my hands would still get cold, unlike with electric gloves which heat the whole hand. It's not too cold here in California, plus I'm too much of a wimp to ride below about 45 degrees so heated grips along with good gloves do the job for me.

    The grips come in three styles with slightly different patterns and lengths. I got the Touring model for the GB and the Sport for my NX250. They glue on with the provided super glue after removing the old grips and cleaning the throttle tube and bar. Wiring routs easily back under the tank to junctions with the controller and fused battery harness. Since they draw almost 4 amps it is recommended to wire them directly to the battery to avoid overloading an existing circuit.

    [​IMG]

    The controller comes with a bracket for mounting to the brake master cylinder clamp but I didn't want to clutter up the GB's dash so instead modified the bracket and mounted it discreetly to a front turn signal stalk inside the left fork ear. It is still accessible and I can still see the led indicators when riding. The so called "intelligent controller" senses when the engine has shut off, then automatically shuts itself off after a couple of minutes to prevent running down the battery. It will also shut off if battery voltage should drop below 11.5V. There are five heat levels, and I find the lowest two levels to be plenty warm for my riding.

    [​IMG]

    When on the highest setting the grips draw a continuous 3.9 amps, so to make sure the GB's charging system could handle the load I used an ammeter to find out what the break-even rpm was. In other words, at what rpm does the system go from discharging the battery to charging. With the grips turned off, there is positive charging at any speed at which the engine will reliably idle. With the grips on the highest setting, the meter showed very slight discharging below about 1,500 rpm and positive charging above that. So the system easily handles the load.

    Finally, I upgraded my gloves to Racer brand Tour FHH. The FHH stands for "For Heated Handgrips." They use minimal lining on the palm side so the heat can come through and for good feel of the controls, but thicker insulation on the top side for warmth. I really like these gloves. Warm hands are happy hands.

    These were purchased from Twisted Throttle in Pittsburgh, I believe. Made for a Honda CB-1, I had to shave them down a couple mms to fit.

    They turned it into something I can spend some time riding, before it was too cramped.

    They sell those offset pegs for $30 on The2Wheels.com , you just have to determine what later model Honda pegs are workable.

    Received fuse box and cover today. Cleaned it up and may just leave it as is or end up painting it to match original silver.

    Happy New Year everyone!

    Just a question for any folks down Florida (U.S.A.) way. There is a website called "OEM PARTZONE" for which an address at 9671 North Dixie Highway, Pompona Beach 33064 is given. According to what appears on the screen they stock EVERYTHING for our machines. I'm old, cynical and more than a little wary. Can anyone verify the existence of this place? I've stopped believing in Santa Claus (and subordinate Clauses) as well. Cheers from Australia!

    Like Santa it's too good to be true and will surely disappoint if you believe too much. That is one of those places that doesn't bother to specify which parts are actually available. You place the order, then they later tell you some items are no longer available. In the meantime they have your contact information for marketing purposes.

    I think I will keep fuse cover unpainted (black). Kind of like the looks a little better. Cleaned up and greased turn signal switch but turns out flasher relay shows intermittent failure - must be loose solder joint as it works when I squeeze the box a little :) will try to resolder or get new one.

    Also plugged empty holes on the block left after removing air pump. And bled brakes too - brake fluid was very contaminated. Checked valve worked great.

    If anyone's looking for a GB500, I just saw a listing on Craigslist for one in upstate NY with an asking price of $3,000. Except for the speedo, tach and headlight buckets being painted black, it looks to be all original including the exhaust, mirrors and bar-end weights. I'd be very tempted to buy it as a back-up for mine if I had the garage space

    I suspect that's a scam, most ads with one picture and a low price are. After you respond they want your email address to send more pictures. Then they have your email.
